The data will be imported line by line, the following description starting with ! serves only the purpose for a better understanding of the file construction.
First mandatory line starts with N (New version) followed by first section, wich describe site conditions.
After a blank line, the information of soil layers are listed line by line.
After the layer based data no further data from this file are being imported. All other potentially existing lines only serve as information.
The number, denoted in nlay , has to agree with the number of layers for which data are being imported.
